Are you ensuring TV (and AVR if used) is powered on before booting the pi?

Quote from monotony

It was once again my bad as I put vc4.inval_delay=5000 after a line break and not immediately on the same line after "quiet" on cmdline.txt

And I'm happy to say that it is working with this value!!! It does not turn on after being powered off!! I'm so happy now!

Okay good to know. It would be helpful if you could confirm whether a smaller number also works (try with 4000, 3000, 2000).

Also try with "vc4.inval_delay=0 vc4.cec_debug=0x100" which I suspect will also fix it.

It would also be useful if any other affected users could test.

Yesterday I did the proposed update to 10.0.2 and since then the 3840x2160 24p video no longer switches to 24p. In 1080p no problem, the tv goes well in 1080p24. Did you have the same problem or do you have a solution please?

It's not something I see (or have seen anyone else reporting).

Probably best to create a new post, including a debug enabled log of you playing a 3840x2160@24 file, where the hdmi mode is not set.

Can you explain, why you have a much darker screen with a clean LE10 than a clean LE9 installation?

LE9 has no support for HDR. If you play a HDR video then the colours will be completely wrong (and typically brighter/more washed out) than they should be.

LE10 does support HDR.

I couldn't get that file to fail to play.

NeB are you using a whitelist?

I suspect your issue is probably related to hdmi cable, but having a whitelist set up (allowing lower resolution/refresh rates to be chosen) will make it less likely you'll hit issues.

See: https://wiki.libreelec.tv/configuration/4k-hdr

The debug log would be useful to see exactly which hdmi is being chosen.

Please note that /sys/module/vc4/parameters/inval_delay value is always 1000 regardless using vc4.inval_delay=5000 or vc4.inval_delay=0 vc4.cec_debug=0x100 at cmdline.txt

That suggests you haven't edited /flash/cmdline.txt correctly.

What does:

cat /flash/cmdline.txt
cat /proc/cmdline

report?

By the way, how to make sure that the update occured?

LibreELEC5:~ # grep . /sys/module/vc4/parameters/*
/sys/module/vc4/parameters/cec_debug:256
/sys/module/vc4/parameters/fkms_max_refresh_rate:85
/sys/module/vc4/parameters/inval_delay:0
/sys/module/vc4/parameters/tv_norm:(null)

If you are not running the correct version, then you won't see the cec_debug/inval_delay entries.

And the values shown should match what you added to cmdline.txt

See post and test build here

There is a test build here.

Place in /storage/.update and reboot to update. It's a Matrix build with some kernel debug options added.

By default it should behave the same as official release. But you can try some modifications by adding options to /flash/cmdline.txt

The default behaviour delays invalidating cec address when hotplug is deasserted for 1000ms (in case it gets reasserted).

That fixes the AVS off/on problem for me with a Panasonic TV and Onkyo reciever.

Try with vc4.inval_delay=5000 (added to end of /flash/cmdline.txt) to increase this delay further.

If that fails, then try another setting.

vc4.inval_delay=0 vc4.cec_debug=0x100

That will ignore the hotplug deasserted message completely. I'd be interested if either (or both) of these helps.

Is it failing to boot, or failing to display a picture? Can you ssh in?

That's the setting. Post a debug enable log when playing a problematic video.

Logical next step is to bump the GPU frequency up a little, however if I even attempt to bump 'gpu_freq' up a mere 50Mhz to 550 then when I try to playback a h265 file, I will immediately lose video output but the OS doesn't crash and the Pi is still reachable via SSH and responds to commands so I can revert and reboot etc..

Disable "adjust refresh rate to match framerate" and I suspect you'll get a picture.

Your overclock is having the same effect as "hdmi_enable_4kp60=1" and something isn't supporting that.

Do you have another hdmi cable or 4k display to test with?

Quote from Baltasar

I have tried the additionof video=HDMI-A-1:D to the command line, and it kind of works

That suggests you don't have a working hotplug connection on HDMI. Try with a diffrent HDMI cable.

Thanks for the update. Regarding deinterlacing support on Pi4, do we need to enable it somewhere on the settings or it's already on?

No, it's automatic when playing an interlaced file.

Interesting. Nightly/master has moved to 5.15 kernel (compared to 5.10 kernel for Matrix) which is one possible explanation.

Probably a kernel display bug, but I'm currently confused.

I just noticed the file played fine for me initially (where I didn't have hdmi_enable_4kp60=1) then later on a different setup did fail.

Looks like the more common [email protected] video doesn't have this failure, but yours of [email protected] does.

I'm guessing the resolution is having some effect on clocks or timing.

I think this is a display issue rather than a video decode issue.

Azurewrath can you remove hdmi_enable_4kp60=1 from config.txt, reboot and try this file again?

Are you saying you get video out of both hdmi ports?

Or are you saying you can get video from one port and audio from the second hdmi port?

The original post read to me like they wanted video from both ports, which I don't believe can be done.

Video from one, and audio from the other can be done.
